SPRING RAIL-FROG.-

SPECIFICATION forming part of Letters Patent No. 729,661, dated June 2,1903. Application filed October 27 1902. Serial No. 129,033 (No model.)

To 0/ whom it may concern:

Be it known that we, WILLIAM H. RABBE, EDWARD W; HARDEN, and MICHAELDEMPSEY, citizens of the United States, residing at Hamilton, in thecounty of Butler and State of Ohio, have jointly invented certain newand useful Improvements in Spring Rail-Frogs, of which the following isa specification.

It is the object of our invention to provide a new and improved springrail-frog in which the spring-pressed movable wing-rail rocks on avertical, pivot located in rear of the meeting points of the point-railsof the main track and siding, while the free end of the movable railtakes into the gap between the ending of the point-rails and thecontinuation of the main rail and is normally held therein byspring-pressure, thereby assuring ease of op-;

eration and preventing loosening of bolts and torsion of parts.

Another object of our improved device is to rock the movable win g-railon a vertical pivot located outside the main and siding rails in rear ofthe points and to provide the free end of the movable Wing-rail with areinforce rail lapping the adjacent ends of the movable wing-rail andcontinuation of the main rail and acting as ariser-rail to protect themeeting ends of those rails from jar.

Another object of our improved device is to provide the movablewing-rail with a diagonally cut end face and to give the movablewing-rail its greatestmovement at that diagonally cut end face, whilethe movable wingrail at its point of greatest movement forms a part ofthe main track parallel with the main-track rail.

This construction provides a spring rail-frog which is compact and cheapin construction, instantly responsive to side pressure from wheelspassingalong the siding without tors'ion of parts, returning instantlyand positively to normal position immediately that the wheels havepassed the movablewing rail along the siding,- insuring the normalretension of the gap-filling part of themovable wing-rail in line withthe main rail,'and 1niniinizingwear of the 'operatinglparts.

Our invention consists in the parts and in the construction,arrangement, and combina tions of parts hereinafter more fully describedand claimed, and the same will be readily understood from the followingdescription and claims,and from the drawings, in which latter Figure ,1is a plan View of our improved device. Fig. 2 is a cross-section takenon the line so a: of Fig; 1, showing the manner of applying the spring.Fig. 3 is an end elevation, partly in section, on the line of Fig. 1,showing the manner of pivoting the movable wing-rail. Fig. 4 is across-section taken on the line 'y y of Fig. 1, showing the means at thefree end of the movable wing-rail for preventing tilting of that rail;and Fig. 5 is a plain view of the reinforce-bar for the movablewing-rail. V

A A represent the main rails, and B B the rails of the siding. V

0 represents the point of the main rail, and D the point of the siding.

The main rail A ends in a diagonal cut F in the longitudinal plane ofthe main rail in advance of the point-rails, thereby forming the gap G,which is filled byrthe free end h of the movable wing rail H. Themovable wing-railhas a diagonal cut h to mate the diagonal cut F. Thefree or swinging end 7'1,

point C. The 'movablewing-rail is pivoted" at its heel or rear end byhaving an upturned and inwardly-projecting bracket 7; fastened to thetrack-plate 1. A U-shaped spanner 7s takes to both sides of theinwardly-projected end k of the bracket 7,1. A reinforce bar L isfastened to the outer side of the web of the movable wing-rail. A bolthaving a squared head It, takes through the spannerplate 71:,reinforce-bar L, and-the movable wing-railand is securely fastenedtherein by the nut 75, a pivot-pin 7; taking through the apertures inthe spanner'plate and bracket for pivotally securing :the movablewing-rail to the plate 1. As seen in the drawings, the

inwardly-projecting end k of the bracket and the spanner-plate 7.2considerably over- IfO the main rail.

lap each other for preventing a tilting of the movable wing-rail out ofits vertical position at its pivoted end and at the same time insure aneasy turning of the rail on its pivot. A reinforce-rail M is properlysecured to the free end of the movable wing-rail, having a portion moverlapping the main rail A for preventing the movable wing-rail beingprojected inwardly beyond its proper limit for alinement with the mainrail. portion m bent outwardly and extending longitudinally of the bentportion I of the movable wing-rail II. The portion m of thereinforce-rail M between the bent portion on and the overlapping portionm lies parallel with the portion h of the wing-rail H and laps thediagonal cuts of the movable wingrail and continuation of the main rail.The reinforce-rail is secured to the movable wingrail by bolts, withfilling-blocks 2 3 between the rails. The reinforce-bar L extendslongitudinally of the movable wing-rail and is bent over upon itself, asshown at Z, for forming a filling-in block between the movable wing-rail and reinforce-rail.

The rails A B A B are rigidly secured together for forming a compactbody to prevent relative creeping of the rails. filling-in block 4 issecurely bolted to and between the tracks A B. A filling-in block 5 issecured to and between the tracks A B, and a filling-in block 6 isbolted to and secured between the point-rails and the rigid wing-rail,the whole being secured to the plates 1 7. Stops 8 limit sidewisedisplacement of the movable wing-rail.

The movable win g-rail is provided with a depression 71 and the outerend of the reinforcerail secured thereto is provided with an in clinedface m for receiving the outer edge of the tread of the wheel, which inpractice is usually of greater diameter than the tread adjacent to thewheel-flange owing to the wear, the reinforce-rail therefore alsoactingas a riser-rail and protecting the adjacent diagonal ends of themovable wing-rail and continuation of the main rail. The rail B is bentat I) for projecting longitudinally of the main rail, but separatedtherefrom by the filling-in block 6 and. having a second outward bent bfor forming a rigid wing-rail for The longitudinal portion h of themovable wing-rail is normally projected to fill the gap by having thesprings N N located in suitable barrels O O and taking about a rod P,plungers p 19' working inthe barrels between the head 13 and nuts 19 onthe rod.

A holddown-bar Q is riveted to the web of the reinforce-rail M. This barmay consist of a piece of metal of substantially the width of the web ofthe rail and be bent back upon itself at its outer end, its inner endsbeing spread, so as to form feet q q, through which the bar is bolted tothe rails. A hood R is secured to a track-plate with the upper innerface of the hood making contact with the It also has a.

Thus a upper edge of the bar for preventing upward movement or tiltingof the movable wing-rail when the wheels pass over it along the mainrail or when pressed sidewardly by the wheels passing over the siding.The holddown-bar and spring are preferably adjacent to each other at thefree end of the movable wingrail, so that the springs may exert'theirpressure directly against the movement of the rail for insuring apositive direct resistance of the shifting of the rail and at the sametime applying the holddown-bar at the point of greatest tendency of themovable wing-rail to tilt, the pivotal point of the movable win grailbeing at its other end in rear of the points of the main and sidingrails.

Having thus fully described our invention,

what we claim as new, and desire to secure by Letters Patent, is- 1. Incombination, with the main and siding point-rails, main and siding railsformed as continnations of the same and forming a gap between saidpoints and the continuation of the main rail, of a movable wing-railswinging from a point in rear of the points of the main and siding railsand having a portion bent and extended longitudinally of the main railwhen in normal position and taking into said gap.
